LORENZO G. STRONG, 0F TACOMA, WASHINGTON.

BEARER FOR PRINTING-PRESSES.

To all `whom Ait may concern: n

Be it known that I, LORENZO Gr. S'inoNc,a

citizen of the United States, residin at'Tal coma, lin the county ot' Pieree'and tate of Washington, have invented certain new and useful Improvements in Bearers for Printnig-Presses; and I do hereby declare the following to be a full., clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same. V

This invention relates to printing resses and particularly to presses of the orden and the Chandler and Price types and the invention particularly resides in improvements in the track construction over which the truck-wheels or rollers operate to transter ink from a source of supply to the form which is mounted on the bed ot the press and toward which in presses of these types a platen moves to carry paper or other ina terial being printed upon toward the form.

It is one of the objects of the present inventionto provide extremely simple, prac- `ticable, inexpensive, etlicient and durable attachments comprising track means for printing presses. A further object ot' the present invention is to enable the ready variation of the degree of pressure of rollers which obtain ink from the source oi supply, upon the form in the press and a further feature is to provide such a means which may be connected to the press with expedition and Awith a minimum requirement ot' change or alteration of the press construction and may be attached with a minimunr expense consistent with the substantial nature of the attachment and to allow for in# stantaneous removal ot the attachment by a simple release of fastening means without .letachinp;` the kfastening means themselves.

' A further object is to provide track members which are capable of ready and independent adjustment so as to vary the plane of the path of travel of the truck rollers or wheels t0 and fro and therefore enable the .accurate and refinedv adjustment ot the tracks so as to secure absolutely uniform pressure at both endsot the inking rollers and also to enable the independent. variai tion of the plane or path otl travel ot the .Specicatioii of Letters Patent.

and elements or parts as more articularly described in the following-speci cation relative to the embodiment of the invention illustrated in the accompanying drawings herein Figure l isy a perspective view of a sutficient portion ot awell-known form of press to illustrate the invention which is shown applied thereto.

Fig. 2 is a cross-section of plane 2-*2 of Fifr. 1.

Ihe type of press illustrated in the accoinpanyiiig drawings has a frame structure including side members with tracks 4 4 on their edges these edges lying in commonv planes at ditl'erent portions and over these tracks are designed to run trucks not illus;

trated, whiclrinclude truck-wheels or rollers 5-5 ot' a width approximating the facel of the tracks Jr-il and these rollers are-mounted on a shaft' 6 on which is mounted anink roller 7 designed to be carried during the oscillation of the truck, up and down the front faces of the tracks 4 and rearwardly and forwardly over the top portions 4 thereof at which portion of the tracks the hiking rollers, of which 7 is one, are 4designed to run over an inking plate shown at 8 to receive therefrom a quantity of the ink which during the operation of the inking; roller is utilized between the rollers and subsequently applied to the type faces in a form mounted between the side frames 3*-3 and not shown.

The. invention in this case consists of members designed to be readily attached to the tracks so as to vary the plane of the path of movement ot the truck rollers as 5 5 during` the portion of their cycle in which they run over or adjacent to the fornr quantity ot' ink applied to the form and also r Further, in a measure protect the rollers by overcoming excessive pressure which, as is commonly known, soon mutilates and renders the rollers useless, especially when these are slightly oversize or generally when new.

Various means have been proposedto vary this contact or kissing of lthe rollers upon the foi-1n and so far as I' am informed the means proposed have been inherently expenfable length and which are adapted to be secured flat-wise upon the faces of the tracks Al, these members have a 'suitable thickness 'to stand the imposed strain and have a reasonable durability under wear. The upper and lower ends ot' the strip portions or the members 10 are shown as beveled down toward, at ll, the track :tace Il, so as to present an incline of gradual angle on which the rollers 6 .will track easily. `lllhile the track members 10 :may be secured 'by suitable means, an elicient and practical torni of device is shown herein by making the members of angle iron plainly shown in Fifi'. 2, the side llane'es l2 of which are designed to extend along the side faces of the press frame. portions and at suitable locations in the side lianges llare provided openings, here shown as extending to the edges or the flanges 12 vso that the track members may be pushed rearwardly against the. track faces 'l, and the flanges 12 pass l beneath the heads ot suitable screws 13, tapped into the frame portions 3 3. From this it u'ill be seen that the only alteration et the press structure required is the tappingand drilling of the holes to receive the fastening screws 13 and obviously any person ot ordinary ability can tap and drill these holes and apply the screws 13, after which the bearers or track members l() can readily be set to the press tracks by passing their slotted portions in the flanges 12 around the screws 13 and then 'tightening up the screws. Further it will be seen that the relative position oi"r the track members l0 as to the track faces il can be quickly varied hy looseningr the screws 13, to a sullieient degree to allow the outward or inward movement ot the bearers to the required position and thenthe screws 13 can loosening' latter.

inseam bearers.

Thus, by the present apparatus, l ain enabled to provide vfor the refined adjustment ot the degree of pressure between the contacting inking rollers and the form iii the press and further it is possible to adjust each ot the members 10 independently of the other so as to provide a uniform contact from one side of the viorm to the other and l am enabled particularly to obtain proper adjustment of the pressure of the truck rollers or Wheels to secure proper contact especially When new rollers are introduced on the press.

What I claim is l l. A bearer `for inkingl roller' truck-Wheels of printing presses, consisting,r of a piece of angle iron one flange of which is adapted to be laid upon the face of the usual track oi' the press, and which. flange has its upper face beveled down to present gradual inclines for the Wheels to track on, and means iior securing the bearer in place, the side flange *being provided with openings, in the form of transverse slots extending in ii'om the edge oilt the flange so that the bearer can be adjusted and detached by the screws without removing the A bearer `for hiking roller truck wheels el printingl presses consisting `el' a plate adapted to be laid upon the tace vof the usual track of the press and having its upper l'ace beveled down to present gradual iiiclines i'or the Wheels to track on, and provided nith means for allixing said plate to the. usual track oic said press in adjustable relation to regulate the kiss of the rollers on the :tace of the torni.
